JESSE SATENSTEIN, OF NEW YORK, N. Y.

BOOK-COVER-MAKING MACHINE.

Specification of Letters Patent.

Patented Jan. 20,; 1920.

Application filed October .15, 1918. Serial No. 258,247.

To all whom it may concern:

Be it known that I, Jnssn SATENSTEIN, a citizen of theUnited States, and a resident of. the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved BoolcCover-Making Machine, of which the following is a full, clear, and exact description.

Among the principal objects which the present invention has in View are: to adapt a machine of the. character mentioned for using a filler more pliable than that usually employed; to adapt a machine of the character mentioned for making soft or flexible covers for books employing the same; to simplify the construction; and to provide for readily replacing the parts of said construction.

Drawings.

Figure 1 is a plan View of a fragment of a book-covering machine and of the transfer mechanism thereof for extracting the paper fillers from the supply thereof and for transferring the same to the leather-covering station. The dotted lines show the transfer mechanism as swung partially over the filler-supply station, while the full lines show the position of the mechanism over the leather-applying station;

Fig. 2 is a detail view on an enlarged scale showing in side elevation, a portion of the transfer mechanism and suction tubes connected therewith, the swinging arm of the mechanism being sectioned to show the interior construction thereof;

Fig. i is a modified form of the yielding guide membersforming part of the invention. I

Description.

The presentinvention relates particularly to improvements in. machines of the character set forth in Patent No. 580.111, issued April 6, 1897, to one A. I. Jacobs, for improvements in machines for making book covers, and more particularly to the means employed therein for; transferring the cover but when the cover boards are thin or quite flexible, the work performed is unsatisfao tory. This failure on the part "of the ma.- chine is largely due to the fact that such cover boards are in part depended upon to cooperate in turning the covering for attachment to the cover boards. I

In the present machine, it willlbe observed that the swinging arm 9 has a channel 10, which in service is connected with means for producing exhaust in saidlchannel. The arm 9 is pivoted on a standard 11 and is providedat the free end with afoot plate 12. The foot plate 12 is suitably secured to a palette 13. The palette 13' is suitably perforated to provide openings for the free ends of suction pipes 14, one end-of each of the pipes being operatively connected with the channel 10. I

By means of the perforations referred to and the pipes 14, which connect the perforations and the channel 10, a suction engagement is exerted upon the two piles of cover fillers 15 when the palette 13 is ex: tended thereove'r and rests thereon. The engagement afforded by the'suction is sufficient to lift the two uppermost of the fillers 15 when the arm 9 is elevated preparatory to rotating to the position where the fillers are lowered upon each of the covers 16. This mechanism is fully set forth in the patent 1 above mentioned.

The fillers 15 are held, in the position substantially as shown in Fig. 1 of the draw} ings. In this position, three of the edges of each of the fillers extend beyond the edge of the palette 13 a distance corresponding with the overhang of the cover 16 when the said fillers are superposed thereon.

In the present invention, the fillers 15 are flexible. To hold the extended edges referred to firmly in position while the margins of the cover 16 are folded thereover, there are provided two series of bowed leaf gs? ease ea es e t, e s-i When the arm 9 is rotated on the standard 11 carrying two of the fillers 15 as described, said fillers are superposed over the cover 16. The mechanism connected with the arm 9 then depresses said arm until the palette 13 and the fillers 15 held thereby rest firmly on the cover 16 and with sufficient pressure to exclude air from between the fillers and cover. The arm 9 continuing to descend, the palette 13, fillers 15, and cover 16 are carried between the plunger plates 19. The plates 19 are connected with machinery for moving the same toward the center of the working position of the palette 13, and are provided with shoes 20, which pass over the upturned edges of the cover 16 to spread the same upon the extended edges of the fillers 15. The palette 13 and parts connected therewith are arrested in the position shown in Fig. 2, where the lower surfaces of the shoes 20 are in line with the upper surfaces of the fillers 15. In this position, the plates 19 are moved toward the palette 13. In such movement of the plates 19, the upturned edges of the cover 16 are engaged and overlaid upon the upper surfaces of the fillers 15, the springs 17 being forced backward by the plates 19, serving, however, to hold the fillers 15 in horizontal arrangement until the shoes 20 pass thereover, and spreading the cover 16 upon said fillers as the plates 19 advance. When the springs 17 are flattened,

,. the shoes 20 are fully extended over the overturned edges of the cover 16. While the plates 19 are held in this position, the arm 9 is again depressed to a position where other plates corresponding to the plates 19 are moved in paths perpendicular to the paths of the plates 19 to fold over upturned edges of the cover 16 adjacent the springs 18, which springs 18 are forced back by the advancing plates in a manner corresponding with the method of operation of the. plates 19 and the springs 17. The second folding position is below the plates 19. Thereafter the extended width of the springs 17 permits the edges of the plates 19 to hold the said springs flattened to prevent their springing forward against the edge of the adjacent overturned edge of the cover 16. Having folded the third and fourth sides of the cover 16, the palette is moved to a position for delivery of the united cover and fillers.

The machine is operated to admit air to the channel 10 and therethrough to the pipes 14, relieving the suction engagement on the fillers 15 to permit the falling or stripping of the fillers 15 and cover 16 connected therewith from the palette. The said fillers and cover therefor are advanced to a delivery mechanism which passes the partially completed book cover out of the machine, rolling or pressing the overturned edges in its progress to the delivery station. When the palette has thus released the fillers and cover, the palette is lifted to the position where the arm 9 is rotated about the pivot for the superimposition of the palette on the supply of fillers at theopposite side of the machine.

In the forward movement of the palette it will be observed that the springs 17 and 18 are prevented from expanding until they have passed beyond the control of the plunger plates by which they were previously flattened or contracted.

In the modified form of the invention shown in Fig. 4 of the drawings, presser bars 21 are substituted for the springs 17 and 18. The bars 21 are guided by pins 22,

which are extended from the sides of the palette 13. The bars 21 are maintained in extendedrelation by the springs 23. \Vhen using the modified form of the invention, it will be understood that the plungers 19 strike upon the bars 21 and force the same back against the side of the palette 13, the springs being compressed in correspondence with this action.

Claims.

1. In a book cover making machine, the combination of a swinging arm having a pneumatic channel formed therein; a palette having openings formed therethrough; a plurality of flexible tubes connecting said channel in said arm and said openings in said palette for producing suction at the ends of said openings to hold fillers for book covers while said arm is swinging from one working position to another; a plurality of plungers adapted to fold the extended edges of covering members for said book covers; and yielding members attached to said palette for holding said extended edges in horizontal relation, such members extending in the path of said plungers, said plungers being adapted to flatten said members.

2. A book cover making machine having an integrally operated swinging arm and lifting palette for extracting fillers from one source of supply to deposit the same on a covering member; and a plurality of lifting palette for extracting fillers from one source of supply to deposit the same on a covering member; and a plurality of bowed spring members, the edges whereof extend outward from the edge of said palette to prevent the lift of the edges of said fillers while having the covering material placed thereover, said springs being arranged in paired relation, the members of one pair being higher than the members of the other 10 pair, whereby the palette, arm, and parts carried thereby may be lowered to a position for delivering the covers.
